LUBRlCATOR FOR STEAM CYLlNDERS.

SPECIFICATION forming part of Letters Patent No. 286,473, dated October 9, 1883.

Application filed July 26, 1883, (No model.)

To CbZZ whom it may concern:

Be it known that I, THOMAS A. NAYLOR, residing at Baltimore city, Maryland, have invented certain new and useful Improvements in Lubricators for Steam-Cylinders, of which the following is a specification, reference being had to the accompanying drawing, forming part hereof, in which my invention is illustrated partly in elevation and partly in section, and in which the same letters always mark the same parts.

My invention is designed as an improvement in that class of lubricators used on the steamcylinders of engines, and has for its object to simplify the construction and lessen the cost of such devices, while rendering them more effective in operation; and to these ends it consists in the construction, arrangement, and combination of parts which will be fully described hereinafter, and then pointed out specifically in the claims.

Referring to the drawing by letter, A is the oilcup, made of any desired material and of suitable size. I

B is a removable screw-threaded plug, inserted in an opening in the top of the cup.

C is a tube let into the bottom of the cup,

and extending at its upper end nearly to the top of the cup and at its lower end to a point, 0.

D is a yoke, in the upper side of which is secured the pipe 0, while inits lower side is secured a globe-valve, H, which in its turn is secured by a T-coupling or other suitable junction to the steam-pipe F, connecting with the steam-cylinders. ccis an opening in the lower side or bottom of the cup A, and leads to a valve, 0;, and thence to an outlet, a. The pipe 0 is provided with a regulatingvalve, 0.

G is a glass tube, secured as follows: f is a threaded collar, projecting upward i'rom the globe-valve H, the thread of which engages a ring-nut, 9, around the glass tube. This nut, when turned down, carries with it a gland, e, which presses upon and expands a rubber or other packing-ring, 0', thus securing a firm support and a perfectly tight joint around the lower end of the glass tube. The upper end of the glass tube is secured in substantially the same manner, the collar corresponding to the collar f being formed as part of the yoke I), or of the pipe 0, as desired.

and causes the oil to rise, overflow the tube G, pass down therethrough, forming drops at its lower end, which fall off and pass into the steam-pipe. When it is desired to increase or lessen the amount of overflow of the oil, it can be readily done by opening or closing the regulating-valve H. W'hen sufficient water has formed in the cup to cause all the oil to be expelled, the further condensation will cause the water to overflow and drop through the pipe 0, and, by reason of the lower end being in full view in the glass tube, this state of affairs will be at once detected, and by opening the escape-valve u" the steam will force the water, and any sediment which may have gathered, out of valves and pipes, thoroughly cleansing the oil-cup. The outlet-valve may now be closed, the valve H closed, and the plug B removed to refill the oil-cup.

' Having thus fully described my invention, I

claim and desire to secure by Letters Patent 1. The combination, substantially as de scribed, of the oilcup, the tube 0, opening within and near its top and extending below its bottom, the yoke D, supporting a glass tube, G, and the pipe or casting secured to the steam-pipe, the whole being arranged in a direct vertical line and having proper valves, for the purpose set forth.

2. In combination with the oil-cup having a valved outlet, the tube G, extending from near the top of the oil-cup into a glass tube, the yoke D, supporting said tube, the glass tube secured in said yoke by steam-tight joints, and the steam-pipe, the whole being arranged as and for the purposes set forth.

In testimony whereof I have hereunto setmy hand in the presence of two subscribing witnesses.
